To all-whom t may concern.' y

Be it known that'I, RICHARD SEGGERMAN, a citizen of the United States,residing at F airbury, in the countyof Jefferson and State of Nebraska,have invented certain. new and useful Improvementsin Can-Sterilizing-Apparatus;' and I `do declare thefollowing to be'a full, clear, andexactdescription of the invention, such aswfll enf.

. sive sterilizer particularly adapted'for sterilizing milk or creamcans.

Creamerles and dairies usually number of receiving stations dlstributed'over a relatively wide area and it is to these stations that thedairymen bring the milk and cream to be shipped to the Creamery-ordairy.

The farmer or dairymanlwho' su plies the milk or cream to the stationsin glie outlying districts usually insists upon retaining control of hisownu milk cans for fear they may be lost or for other reasons.Therefore, it is desirable that when the milk or cream is dumpedfrom'the farmers can that such can be sterilized preparatory to sendingit back to its owner. l

It is, therefore, the purpose of my invention to provide a sterilizer,the cost of which will not be prohibitive for small `stations and whichwill eiiiciently sterilize the can,

wash it-and dry it so thatit can be returned in a sanitary condition. v

be apparent by reference to the following description in.connectionnwith the accompanying drawings, in whichv Fig. 1 is aperspective view of a sterilizing washer constructed in accordance withmy invention, and

Fig. 2 is a'rvertical,v longitudinal, sectional viewthrongh thesterilizer and washer.

1 designates a supportin frame or ystand within which is 'mounte lapluralityI of burners2, which may be supplied with fuel oil from asuitable source es, for enample,

the tank or reservoir 3. The source'of heat supply, however, isimmaterial.

have a- Supported uponthe frame or table .1 is a steam generator 4having an inlet 5 at the top and provided with a pressure gauge 6 Iwhereby the pressure`with1nthe 'tank may be observed. The upper portionof the steam generator tank 4 constitutes a steam dome, as at 7,from-which vleads a steam pipe 8, discharging through a nozzle 9,concentric with the conical, hoppershaped portion 10 of a can-supportingtable 11, one end ofwliich may lbesupported by the tank 4 and the otherb awash ltank 12, supported on the standar s 13.

-.The pipe 8 is provided with a rightangu- -lar extension 14, which isthe connector between the nozzle 9 and the pipe 8 and the connector isprovided with a valve 15 by which the flow of steam may be admitted toand cut off from the nozzle 9.V

There. is another pipe l'leading from the pipe 8 below the pipe 14 andthis pipe is.'

termed a condensate pipe, `provided with a valve 17 and discharging-intothe tank 12 to warm the water therein. It is desirable that the pipe 16be on a lower planel than the pipe 14 so that any condensated steam willaccumulatey therein, read to flow into `the tank 12 when the valvels'opened andv not discharge through the nozzle 19, asf will be apparentby reference to Fig. 1.

The tank 12 has a discharge nozzle 18 by means of which it may bedrained. i

A hot air pipe or conduit having a lateral, intermediate portion 19, adependin inlet end 2O and an upstanding outlet en 21, is

carried by the' frame 1 andthe intermediate portion 19 lies over theburners 2 so that the air within the'portion 19 may beheated,

causing a 4draft through the inlet 22 so that there will be acirculation of air up through -The novel construction 'of the inventionwill`- the discharge end 23 .ofthe heater pipe.

There are spacing cleats 24 and 25 on the table 1d.,k and on opposite.sides of the discharge 23 of the'heaterlpipe, as will be apparent byreference 1U fFlge i1'.VA if* Y When the farmer or dairym'an brings themilk to the` receiving Statimi, the can may be tilted on the-table 11to-discharge into the open or funnel-shaped portion 10, `it beingunderstood that there willbeaniother can '26 beneath the funnel orhopper to receive the discharged contents of the rst named can, shown'in dotted lines in Fig. 2 as 27'.

Then the perator will`open the valve to admit steam from the nozzle 19into the can 2:? so as to dislodge anyadher'ing particles of butterfatsothat these may drop into the hopper and into the can 26. 'The can may'then'be swung over the end of the table 11 into the washing vat or tank12, the temperature of the water vin the vat being maintained by thecondensate discharging from pipe 16 butin the event that it is necessaryto bring the 'temperature higher than possible by the condensate, livesteam may be admitted from the pipe 8.

The can is thoroughly Washed in the vatand then again placed over thenozzle 9 to s terilize the interior thereof. It is then placed over thedischarge end 23 -of the drier, the end of the can resting upon thecleats 24 and 25 that fresh Ahot air may.

`be admitted into the can, from the heater pipe and theld'amp airexhausted `between the cleats 24 and 25 and the table 11; The heated airentering the can from the nozzle 23 will 'dry the 'interior thereofand'yrestore it to itsoriginal condition, ready t`o' again be used.

-By using my improved forni of 'drier it 'will be 'readily seen thatonly pure hot air is used in drying the can and that no fumes from theburner can'enterythe drier pi e to contaminate-the air and cause a foulolor 'in the can after the f process is completed. f Ofcourse,`theinitial sterilization may take placefrom th'ejnozzl'e-S)vbutl the hot dry air -willlalso tend to renderthe interior of the cansterile.

From the foregoing it'lvrvill Abe 'apparent that a device constructed inaccordance with my invention Willbe inexpensive, durable and efficientin cleaning and sterilizing vessels, such as milk cans and vthelike.

What I claim and desire to seciir'e by Letl ters-Patent is: y

1. A device of the 'class described comprising a wash' tank and asteam-generator v's aced one from the other, a table bridging A t e 'gapbetv'veen them and supported by the wash' tank'and steam generator, aunnel-shaped can-receiving member in the table, a steam nozzleextendingthrough the funnelshaped member and connected to the steam generator,means for-- controlling theI steam admitted to the Steam nozzle, and .a

condensate pipeV communicating with the source of steam supply anddischarging into the Wash tank( 3.1m a device of the class described, a'

. table having a funnel-shaped recess to receive the inverted ends ofmilk cans, a steam kjet nozzle concentric with and extending through thefunnelshaped-recess, al wash tank adjacent the funnel-shaped recess, a

'steam'supplypipe for said nozzle, a condensate' plpe' located beneathsaid nozzle and adapted to receive the condensation from said steam pipeand` saidlnozzle, and

a valve for discharging said condensate pipe into lsaid jwash' tank.

r In testimonyl whereof I ax my signature. Y
